Description

I am trying to read a PMTiles file from s3 using signed URLs

I expect this to allow the pmtiles to be read through leafmap and rendered, but instead I got a validation that the file path must ending .pmtiles.

What I Did

import leafmap.foliumap as leafmap
import boto3
s3_client = boto3.client('s3')
signed_url =  s3_client.generate_presigned_url(
    'get_object',
    Params={'Bucket': myBucket, 'Key': "somePrefix/filename.pmtiles"},
    ExpiresIn=60 * 60 * 4 # 4 hours
)

m = leafmap.Map()
m.add_pmtiles(
    signed_url, name="PMTiles", style=leafmap.pmtiles_style(signed_url), overlay=True, show=True, zoom_to_layer=True
)
m

gives:

      6 )

ValueError: Input file must be a .pmtiles file.

my work around until we merge and release this:

signed_url = get_signed_url(s3_uri) + "&extension=.pmtiles"

Thanks for the fix. I will release a new version tonight
